To all 'whom it may concern:

Be it known that I, ANDREW Gr. PAUL, a citizen of the United States, residing in- Boston, in the ,county of Sudolk and4 State of Massachusetts, have invented a new and useful Improvement in Heating Systems, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawings, which form a part hereof.

rlhis invention relates to a heating system wherein steam or other suitable heating agent is circulated for the purpose of conveying and imparting heat to the places desired,` and it consists in an improved con# struction and arrangement of the parts of such system.

The invention consists in the combination of a heater or radiator, a valve for 'controllingthe operation of the same, a motor connected with said valve, the valve casing having a Huid pressure chamber on one side of said motor, a suitable vent for said chamber, a Huid pressure device adapted either fluid pressure chamber with fluid under pressure, or to exhaustl the pressure from said chamber, a pipe connecting the device with the fluid pressure chamber, and a second motor controlling said pipe and connected with a heater or,y radiatorl so as to be operated by the pressure therein.

ln the best form of my invention, the first mentioned motor is provided wit-h an equalizing passage connecting the chambers on opposite sides ofthe motor whereby when the Huid pressure device is cut ott from the fluid pressure chamber, the pressure in the chambers 'on opposite sides ofthe motor will be equalized through the equalizing passage. In the best form of my invention also, y l employ an .exhausting device for exhaust* ing the pressure from the Huid pressure chamber. This part of my invention also contemplates the employment of a thermostat to be placed in any desirable position, and adapted to control the pipe or passage connecting the iuid pressure chamber of the second motor with the heater or radiator.` My invention also consists in other features of construction and combinations of or reservoir 5.

6 is a check valve on the discharge pipe.

7 is a vapor pipe provided with any suitable form of valve 8.

9 isa pipe through which the water may be discharged or pumped to the boiler or discharged in any other'suitable manner.

l0 is an air pipe connected with the exhauster and with any suitable form of air valve 12.

33 is a piston provided at its lower end with what leave piston and the wall of the casing, the equalizing passage operating as sa vent for the fluid pressure chamber 42 the piston.

36 is a coiled spring adapted to press upon the upper end of the piston, and the tension Slmllar numbers indicate similar parts in the different gures.

Figure 1 shows one form of my invention i in w ich the eXhauster is connected with the discharge pipe, and the fluid pressure chamr37 screwlng into the upper'part of the cas- 4 is the discharge pipe leading to the tank by means of the pipe 16 with the radiator.-

31' is a suitable casing provided at itsy which is above ing. 38 is the pipe connecting this valve with the radiator.

39 is a valve on the discharge pipe having separate passages for the escape of the air and water of condensation. The special form of t-his valve isl shown and claimed in my Patent No. 771,744 dated Oct. 4, 1904. I do not claim it in this application separately. The construction of this valve is shown in Fig. 5.

40 is an exhauster connected with the dischargel pipe.

41 is a pipe connecting the fluid pressure chamber 42 of the supply valve with the discharge pipe, through and by means of the side passage or air passage of the discharge valve 39. The pipe 41 is provided with an ordinary hand valve 43 by means of which the pipe may beshut oft'.

44 is a valve in the pipe 41 which is controlled by the diaphragm 13 through and by means of the connecting rod 45. In this form of 1apparatus the air pipe 10 is connected with the pipe 41 in the manner shown. l

The operation of this form of my invention is as follows: Assuming that the valve 25 is open, when the pressure in the radiator falls below the desired or predetermined point, the diaphragm 13 is moved so as to open the valve 44 in the pipe 41. With the valve 25 operated by the thermostat being open and the valve 44 being open, the eX- hauster operating through the pipe 41 decreases the pressure in the fluid pressure chamber 42 and lifts the piston 33, thereby opening the supply port. 32 and admitting the heating vehicle to the radiator. When the pressure in the radiator increases to the desired or predetermined point, the valve 44 is closed by the diaphragm 13.v The Huid in the chamber of the supply valve below the piston 33 escapes through the equalizing passage 35 or vent into the fluid pressure chamber 42. When the pressures in these two chambers are suliiciently equalized the piston 33 falls and the supply port is closed. At the same time the air 'and water are drawn out positively and automatically through the valve 39. By connecting the air pipe 10 with the pipe 41 in the manner shown, when the valve 44 is opened the air is removed from the radiator through the pipe 10 at the same time that the supply valve is opened. The removal of air through the,pipe 41 is stopped when the supply valve is closed. The thermostat 24 and the valve 25 control the pipe 16 -in the manner and for the purpose already set forth.

Y The construction of the valve 39 is shown inFig. 5 in which 57 is the valve casing, 58 is a port at its lower end for the discharge of the water, 59 is a piston or pressure motor provided at its lower end with a valve 60 adapted toclose the p-ort 58, 61 is a passage for air or gas or vapor between the piston and the wall of the casing, 62 is a fluid pressure chamber above the piston, 63 is a passage in the casing connecting the iuid pressure chamber with the discharge pipe beyond the discharge port 58, 64 is a spring one end of which bears against the upper side of the piston and the other end of which bears againstthe lower surface of a screw 65 by means of which screw the tension of the spring can be varied and adjusted, and 66 is a cap adapted to cover and protect the screw 65.

` 1n Fig. 3 another form of my improved system is shown, in which the parts are the same as already described with the following differences: 50 is a diaphragm controlling the supply valve through and by means of a rod 51. 52 is a pipe leading from the fluid pressure chamber of the diaphragm to a separate eXhauster 53. rIhe pipe 52 is provided with a valve 54 which is controlled by the diaphragm 13 in the manner already described. The air pipe 10 is connected with the pipe 52 as shown, and the pipe 52 between this connection and the supply valve is provided with a v alve 55 operated by thermostat 56. The discharge pipe is provided with the valve 39 already described, and the exhauster 40. The operation of this form of my invention is as follows: Assuming that the valve 55 is open, when the pressure in the radiator rises above the desired or predetermined point, the valve 54. is closed. Some suitable vent 70 is provided in connection with the iuid pressure chamber of the diaphragm 50 by means of which, under these conditions, the pressure is equalized on both sides of the diaphragm 50,

and the supply valve is thereby shut. This vent can be provided by making an air hole 1 or pin hole through the casing which suports the diaphragm 50. When the pressure alls in the radiator below the desired or predetermined point, the valve 54 is opened and the diaphragm 50 is caused to open the supply valve and admit the heating vehicle. The thermostat 56 controls the valve 55 and thereby controls the operation of the sup-ply valve in the manner already fully explained. The valve 55 is constructed like the valve 25, see Fig. 4.-

Some of the advantages secured by my invention are as follows: The heat imparted by the system is accurately and nicely controlled, the Apressure of the heating vehicle in the system or heater serving to control or operate at any predetermined point a valve or other controlling means by which the effective heating work of the system is regulated. To this regulation of the system isl other position Where it will be exposed to the fluid pressure chamber, a valve in said the regulating temperature. At the same pipe, a second motor controlling said valve time the air and Water of condensation are and connected With a heater or radiator so positively and thoroughly removed from the as to be operated by the pressure therein,
